MegaMacs offers the refurbished Apple iMac Intel Core 2 Duo 2GHz 17" All-in-One Desktop, model no. MA590LL/A, for $299.99 plus around $20 for shipping. That's $51 under last month's mention and the best price we've seen for this system. (It's also $96 under the lowest total price we could find for a used unit elsewhere.) It features an Intel Core 2 Duo T7200 2GHz dual-core processor, 17" 1440x900 LCD, 1GB RAM, 160GB 7200 rpm hard drive, DVD burner, 802.11n wireless, Gigabit Ethernet, Bluetooth, iSight webcam, and Mac OS X 10.6 Snow Leopard. Deal ends July 24.

A 30-day MegaMacs warranty applies.
